Serial No. 6 .1 N m' m To all whom it may concern.- 1 Figs. 1 and 2 the oiler is cast with,and forms Be it known that I, SAMUEL V. KENNEDY,. part of, a bushing'C which is mounted within of St. Paul, Minnesota, have invented a new the frame D and forms the bearing forthe and useful Improvement in Lubricating Deshaft B. In Fig. 3, the oil device is shown 5 vices, of which the following isadescription, separate from the bushing 0, being screwreferring to the accompanying drawings, threaded into it as clearly indicated. which form a part of this specification. The oiler consists primarily of acup-shaped My invention is particularly applicable to or chambered portionFcontaining the oil pasharvesters and like machinery used in the sage or oil cup-G, which extends toward the 1 0 presence of considerable dust or fine partishaft and permits the oil to run on to the mo'vcles which are likely to get into the oil cups ing surface of the shaft.

Such machinery being generally As the details of the chambered portion F, x 5 used by men skilled in the particular agriand the other details of my device are very cultural or other art for which they are insimilar throughout the figures, I will first detended, rather than skilled mechanics or enscribe the mounting of the device as a whole, gineers, must of necessity be of comparaand then set forth the details, operation and tively simple and durable construction, and purposes, of the various elements which com- 20 must not require too great delicacyof mani pupose it.

lation. In Figs. 1 and 2, the oiler is cast integrally It is the object of the present invention to with the bushing or sleeve 0, preferably of produce an oiling device which may be some anti-friction metal. The bushing or cheaply manufactured and applied, and simsleeve 0 is formed to fit and snugly surround 25 ple in operation and effective in keeping out the shaftB, and is fitted to and extends the particles of grass, grain, dust or other through theframe plate D, resting against foreign matters. the shoulder c and held,,from turning by To these and certain other incidental purmeans of the two small lugs or ears 0' which poses my invention is embodied in an oil dc engage the corresponding lug or card on the o vice and its several parts constructed, ar-' frame. These lugs are in such a position ranged, combined and used in a manner subthat the oil cup or oil passage G is on the stantially similar to that hereinafter deupper side of the shaft, permitting the oil to scribed, illustrated, and claimed. flow down on to the shaft by gravity.

The device being of extreme simplicity, will In Figs. 3,4 and 5-my oil device is formed 3 5 be best understood by the accompanying separate from the bushing or sleeve 0 and drawings, whereinscrew threaded into it, producing an ex- Figure 1 is an axial view of my device as tremely novel, convenient and satisfactory applied to one of the shafts of the harvester. form of -oiler which may be readily applied Fig. 2 is a longitudinal section through the to any sleeve, it being only necessary to tap 4o center of the device in the plane of the axis and screw-thread the ordinary oil hole in the of the shaft. Fig. 3 is a transverse section of sleeve, if the sleeve is not already prepared a modification. Figs. 4, ,5, 6 and 7 are rear, to receive the oiler. The sleeve will, in most bottom and two face views of the same.

In seen in Figs. 3 and 5, is struck down into a threads is very important as it enables a cast thread to be safely employed notwithstanding the looseness of its tit.

The passage-way G may be angular, as clearly shown in Fig. 3, or may be any form that is desired. The form shown in Fig. 3 recommends itself as being very com enient for the insertion of a nozzle of an oil can. In order to cover the mouth of the oil passage, the chambered portion F is provided with a circular plate-shaped face V, upon which the cover II is mounted and turns. In Figs. 9 and 10 the face of this portion'V,and the cover H are eachshown in full face view. The cover as mounted in position, is shown, in Figs. 3 and 6, open, and in 7 andS closed. The mouth of the passage-way G is clearly indicated, and the cover H is provided with a recessed or cutaway portion h, which may be turned opposite the mouth of the oil passage G as in Fig. 6, leaving the mouthentirely open for the insertion of the nozzle of an oil can. A short projecting ear or lug h' opposite to the recess h forms a handle by which the cover may be readily turned upon its pivot K. The pivot K may be either a rivet or a screw passing through central openings through the cover H and plate V. In the face of the plate and of the cover are semi-circular channels or recesses G and H which, when brought opposite each other, form a circular receptacle for the spring J, as most clearly seen in Figs. 2, 3 and 8. These recesses G, and H, are so placed that the springforces the cover into the position shown in Fig. 7,-'-the projection or stop h resting against the stationary stop 9', and the cover, in conjunction with the projection h covering the mouth of the oil passage G. When it is desired to introduce oil, the cover is turned and the oil passage uncovered, by means of the lug or ear h, and when the oil has been introduced the cover is released, closing the mouth of the oil passage, and effectually preventing the entrance of dust or small particles of grain, grass and'other foreign matter. As the parts are very roughly and cheaply made, it may, in many cases, be necessary to close the oil passage by hand, relying on the spring only to hold it closed, and-in many cases I entirely omit'the spring, as the weight of theprojections h and h in itself tends to keep the cover closed; and the opposite portion, being recessed at h, increases the action of gravity in holding the parts imposition;

Such briefly is a description or the preferred embodimentsof 'my invention, but I do not wish it to be understood that I 'am limited to the precise details described and illustrated except so far as they are clearly essential to the carrying out of the principles and purposes of the invention, for

I claim, and desire to secure by these Letters Patent of the United States, together with all such modifications and additions as may be made by mere skill in the art without departing from the principles involved, and with only the limitations and restrictions expressed or by law implied in view of the prior art, the following:

1. In combination with a bushing or bearing, an oil device having an oil passage G and a pivoted or rotary cover H and a spring, located in recesses G, H, whereby the said cover may close the said oil passage and be held in position by the action of the spring, or may be opened for the supplying of oil, subst-antially as and for the purposes set forth.

2. In combination with a sleeve,bushing or bearing, an oil device provided with screwthreaded extension g and cast or otherwise roughly formed, in combination'with a portion, lug, or ear, f arranged to be struck down or otherwise brought into engagement with the surface into which the said device is screw th-reade'd for the purpose of preventing the unscrewing, substantially as set forth.

3. In combination as an oil device constructed to be used in the manner described, a chambered portion F provided with a screw threaded extension 9 and a projecting flange or ear f, and a rotary cover H arranged to 5 be turned into position either to cover the mouth of the oil passage, or to leave the same unobstructed, substantially as set forth.

4. In combination in an oiling device and for the purposes described, the plate shaped portion V, cover H pivoted thereto and formed to open or close the mouth of the oil passage or cup, and a spring J operating in the concentric recesses G, H to close the said cover over the said mouth, substantially as set forth. 5. In combination with a sleeve bushing or bearing, a cast brass or cast metal oil device provided with a screw thread extension arranged to fit roughly within a correspondin gly screw-threaded portion of the said sleeve or bushing, and a flanged portion,lug,or e'ar, f and co operating recess 0", the said portion, lug, or ear,f being formed to clear the said recess during the action of screwing the said device into place and to then be bent into permanent engagement with the said recess c', substantially as set forth.

In testimony whereof I have hereunto set my hand this 36 day of July, A. D. 1894, at the said city of St. Paul, Minnesota, and in the presenceof the two subscribing witnesses.
